Really now, this is year 2010, in the age of Google. If you can't learn to use it then have someone teach you. And I don't mean make a new topic asking "what is Google? where can i download it?"

Most of your questions could be answered by yourself by either searching google or this forum. Please help yourself before asking others to help you, for simple things like this. You'll get your answers a lot more faster and be less of an inconvenience to everyone else. I bet that RudySchneider used google to provide you with that answer. Thanks for making him do your work for you.

Also, here's a hint to make your quest for knowledge easier...if you want the definition of a word, type "define:whatever" in the google search field and it'll come up with a list of definitions for "whatever".
